IMPS-4400 Profile Moisture Measurement

Profile Moisture Measurement Systems which use an array of RF sensors to measure the moisture profile of boards. This system is widely used at the production of gypsum boards and other boards to optimize and balance the dryer. The IMPS-4400 is an important tool for production optimization and reduces the loss of production and energy usage by increasing the efficiency.


The IMPS-4400 is an Instant Moisture Profiling System (IMPS) that employs an array of 2 inch Radio Frequency Dielectric Sensors used to relate directly to the moisture content of your product. This array can span a wide area allowing up to 128 sensors to measure the true moisture composition of your product.

It is equipped with a powerful set of software tools used for comprehensive data logging and statistical analysis that provides a real-time moisture profile of manufacturing lines having multiple-decks and multiple-products. Optionally, the IMPS-4400 comes with an I/O module that provides moisture data outputs to your Plant Master Control Panel.

The RF Sensor Array provides the source of the Radio Frequency Dielectric Measurement. Each sensor has a 2” resolution (50mm) and can be combined to cover a 256” (6.5m) width. This array acts as a collective moisture profiling measurement isolating each sensor’s measurement to form a consecutive row of multiple moisture sensors. The IMPS-4400 is not a single moisture sensor but a system containing numerous moisture sensors.

The Data Concentrator multiplexes the data received from the RF Sensor Array and combines this high volume of data at a sample rate of 30mS (33 samples per second). Its intelligent design gives the IMPS-4400 the speed to show the true moisture content of your product in real-time.

IMPS-4400 Controller
Perhaps the real power of the IMPS-4400 lies within the IMPS-4400 Controller. Graphical representations of data collected from numerous individual sensors using a Radio Frequency Dielectric Measurement are a powerful combination of technologies. Visualizing moisture profiles from a variety of perspectives with the IMPS-4400 proprietary software takes you from a simple moisture measurement to a better understanding of your production process as a whole.

CONTROLLER / PLC (User Defined)
The IMPS-4400 comes with an I/O option that translates data from the IMPS-4400 Controller to an input in your process control system. These inputs include: 4-20mA, 0-10VDC and 0-5VDC
